Impact Of Transportation Infrastructure On China's Import And Export Trade

The two world waves characterized by the reduction in transportation costs have promoted the rapid development of world trade and highlighted the importance of the construction of transportation infrastructure.As early as 1996,the Chinese government included the strengthening of investment in transportation infrastructure in the national economic development plan.Since the beginning of the new century,China's transportation infrastructure construction has achieved breakthrough development.At the same time,China's foreign trade has also achieved rapid growth.Obviously,the development of transport infrastructure has played a unique role in the growth of China's import and export trade.How does the transport infrastructure affect the import and export trade and what is its mechanism of action? Scholars in different fields have conducted a lot of research from different perspectives.However,in the existing literature on the impact of transport infrastructure on import and export trade,traditional economic theories and methods are often used,ignoring the spatial impact of transport infrastructure on the economic system.In recent years,with the development of new trade theories,new economic geography theory and spatial econometrics,the influence of spatial factors on economic systems has attracted the attention and research of many scholars.However,few scholars use Chinese provinces as research samples to examine the impact of spatial spillover effects of transport infrastructure on the development of China's import and export trade.Based on this,this paper uses 30 provinces,cities and autonomous regions(excluding Tibet,Hong Kong,Macau,and Taiwan)as research units,and uses spatial exploratory analysis methods on empirical methods based on the theory of international trade theory and the new economic geography theory.,Spatial Lag Model(SLM)and Spatial Dubin Model(SDM)to assess the impact of spillover effects of transport infrastructure on China's import and export trade,to rationally plan the construction of transportation networks in China,strengthen the degree of internationalization,andparticipate extensively in the international division of labor.China's import and export trade provides stable reference for development.This article explains the main content from the following sections:First of all,this article explains the relationship between the two scholars by combing and in-depth understanding of transportation infrastructure and international trade research: starting from the perspective of transportation cost,trade facilitation,and corporate positioning,and the transportation infrastructure A more in-depth discussion of the spillover effects of import and export trade.Second,it analyzes the theoretical origins and theoretical models of the relationship between transport infrastructure and international trade.First of all,it analyzes the theoretical support for the spatial spillover effect of transportation infrastructure.Research shows that the spatial dependence of economic development,the external attributes of transport infrastructure,and network attributes are the preconditions for its creation.Then,under the premise of combing the literature on the relationship between transport and international trade in the theory of international trade and the theory of new economic geography,the relationship between the two was analyzed based on the regional spillover model.The study concluded that interregional trade will increase with the improvement of the construction of traffic networks,and that there is a spillover effect on trade,which lays a theoretical foundation for the empirical test of this paper.Finally,an empirical analysis of the impact of transport infrastructure on the spillovers of import and export trade.The first part describes the basic characteristics of spatial data of transport infrastructure and China's import and export trade variables through spatial exploratory empirical methods.The study concluded that there is a significant spatial autocorrelation between transport infrastructure and import and export trade.In the second part,the spillover effects of transport infrastructure on China's import and export trade are decomposed into related spillovers and direct spillovers,and an empirical analysis is conducted using the spatial panel model.The study considers that the impact of transport infrastructure on the import and export trade will come into play through the three methods of correlation spillover effect,direct spillover effect and direct influence on economic variables,and the spillover effects of different types of transport infrastructure are different.In the third part,this paper analyzes the development status of the transportation infrastructure and import/export trade scales in the three major regions of China's eastern,central and western regions.The study finds that there are significant areas in terms of both the scale of transport infrastructure and the development of import and export trade.Based on this difference,we conducted an empirical analysis of the three major regions through the spatial Dubin panel model.The analysis concludes that there are spillover effects of highway and railway infrastructure on the import and export trade in eastern China,central China and the western regions.Different regions have different ways of expression.For the eastern region,the spillover effect of highways is significantly positive,and the spillover effect of railway facilities is significantly negative.For the central region,there is a spatial spillover effect of both road and railway infrastructure,but the impact is not significant;for the western region,despite The spillover coefficients for roads and railways are positive,but the spillage of highway infrastructure is not significant and the spillover of railway infrastructure is significant.In general,transport infrastructure has spatial spillover effect on China's import and export trade and there are regional differences.This paper analyzes this problem through theory and model and uses the data of 30 provinces in China as the research object to use the space panel model for empirical analysis.Finally,draw conclusions based on the analysis and propose corresponding policy recommendations.
